Twelve. Here is how: Using cents rather than decimal dollars: 5n + 10d + 25q = 640 Express the numbers of nickels and quarters in terms of the number of dimes: # of nickels = twice the # of dimes ==> n = 2d # of quarters = 5 less than the # of dimes ==> q = d-5 Substitute for n & q in original equation: 5(2d) + 10d + 25(d-5) = 640 45d - 125 = 640 45d = 765 d = 17 ==> 170 = $1.70 n = 34 ==> 170 = $1.70 q = 12 ==> 300 = $3.00 . . . . . . . . . Total = $6.40

You need to define variables for the different types of coins, write the corresponding equations, then solve them. One equation for each fact. Here are the equations:5N + 10D + 25Q = 1250 D = 2N Q = 2D

Nickles - 10 $0.50dimes - 20 $2.00quarters - 40 $10.000.50+2.00+10.00 = $12.50 containing 40 quarters---Here's how to solve this with Algebra :Let N be the number of nickels, so that2N is the number of dimes, and2(2N) or 4N is the number of quarters.A nickel is 5 cents, a dime is 10 cents, and a quarter is 25 cents,and the total in the cash register is $12.50Multiplying by their cents values, we have5(N) plus 10(2N) plus 25 (4N) = 12505N + 20N + 100N = 1250125 N = 1250N= 10So the number of nickels is 10, dimes 20, and quarters 40.
A man has a mixture of nickels dimes and quarters in his pocket. He has 12 coins in all with a total of $1.20. If he had twice as many dimes as quarters how many of each coin does he have?
Each quarter is 25, and he has X quarters. Each dime is 10, and he has 2X dimes. Each nickel is 5. He has 12 coins in total, and all of the ones that are not quarters or dimes are nickels. Since quarters and dimes have to come in sets of 3, that's 12-3X. 25X + 10(2X) + 5(12-3X) = 120 25X + 20X - 15X + 60 =120 30X + 60 = 120 30X = 60 X = 2 He has 2 quarters, 4 dimes, and 6 nickels. To double check let's add them up: (2 * 25) + (4* 10) + (6 * 5) = 120
